What does it mean when you have a hemangioma on your liver?
A liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass in the liver made up of a tangle of blood vessels. Also known as hepatic hemangiomas or cavernous hemangiomas, these liver masses are common and are estimated to occur in up to 20% of the population.
Is liver hemangioma echogenic?
The echogenicity of hepatic parenchyma influences the US appearance of a hemangioma. Because of the increased echogenicity of attenuating fatty liver parenchyma, diffuse fatty infiltration may lead to an atypical echo-poor appearance (6) (Fig. 8).
What is a echogenic lesion?
An echogenic breast mass is defined as a lesion that is hyperechoic in comparison with subcutaneous adipose tissue at ultrasonography (US), in accordance with the US lexicon of the Breast Imaging Reporting and Data System (BI-RADS) of the American College of Radiology (1).
What does echogenic lesion in the liver mean?
A hyperechoic liver lesion on ultrasound can arise from a number of entities, both benign and malignant. A benign hepatic hemangioma is the most common entity encountered, but in patients with atypical findings or risk for malignancy, other entities must be considered. Benign.
What is echogenic liver?
An echogenic liver is defined as increased echogenicity of the liver parenchyma compared with the renal cortex. The prevalence of echogenic liver is approximately 13% to 20%. In most clinical settings, increased liver echogenicity is simply attributed to hepatic steatosis.
What does echogenic lesion mean?
INTRODUCTION. According to the ultrasonography lexicon of the Breast Imaging-Reporting and Data System of the American College of Radiology,(1) an echogenic breast lesion is defined as a lesion that is hyperechoic in comparison to the surrounding subcutaneous adipose tissue on ultrasonography.
When should a liver hemangioma be removed?
Abdominal pain or discomfort associated with liver hemangioma is the most common indication for surgical excision. Increasing size or intratumoral thrombosis or hemorrhage can cause pain, as a result of liver capsule distension.
What are the characteristic ultrasound features of liver hemangioma?
Most of the lesions were hemangiomas. One of the purposes of this study was to determine the characteristic ultrasound features for liver hemangioma. Small (less than 2 cm), homogeneous, echogenic, well-circumscribed, subcapsular lesions almost prove their hemangiomatous nature.
What is the most common hyperechogenicity liver lesion?
hepatic hemangioma : commonest hyperechoic liver lesion by far (present in 4% of the population) 1,4 The presence of hyperechogenicity can be a result of fat within a liver lesion 2, although some non-fat-containing lesions may also be echogenic (e.g. hepatic hemangioma).
What is the clinical significance of focal echogenic liver lesions?
Clinical significance of focal echogenic liver lesions During a 4-year period, 53 focal echogenic liver lesions were demonstrated by sonography in 41 patients, in whom there was no evidence of metastatic origin. Most of the lesions were hemangiomas.
What causes liver hemangiomas to grow?
The female hormone estrogen, which increases during pregnancy, is believed to cause some liver hemangiomas to grow larger. Very rarely, a growing hemangioma can cause signs and symptoms that may require treatment, including pain in the upper right quadrant of the abdomen, abdominal bloating or nausea.
